for love of my father and a distaste of his brainworms i'm selfishly gonna hold his ass down and make him drink deeply of the mystik röt
I'd opt for either Putin or the current director of the CIA.
Putin for obvious reasons.
The CIA director for their ability to leak all sorts of information while critically undermining the efforts of the CIA from within, essentially hamstringing the CIA for decades to come and thus allowing countries especially in Africa and South America the breathing room to stray further leftwards without the threat of being destabilised or overthrown.
I think it would be a good idea to inject marx juice into a union president, i think you would get most amount of radicalization from that
You know what, turning Lula into a radical stalinist may actually work, with all the influence he has in the unions in brazil, plus the workers party and he has good relations with the PCB
Also Evo could work too
